Bright
250 lumens is approx the same, as you would get from a 20w household lightbulb.
Its about the Same as a 311 watt light bulb
It is equivalent to a 75 watt incandescent bulb
Lumens measures how bright it is, watts measures how much electric power it uses up. An old-type incandescent bulb produces about 10 lumens per watt. A halogen produce about 13 lumens per watt. A fluorescent (energy saving) bulb produces about 50 lumens per watt. LEDs produce somewhere around the same as a fluorescent.

one lightening candle is one lumens, 120 lumens is 120 candles togher. Like IMALENT 4000Lumens, DDT40,imagine how it is bright.
High Bright: 1700 Lumens Eco Mode: 1360 Lumens http://www.infocus.com/Support/Products/Projectors/IN24.aspx
This is very bright for indoor lighting, the equivalent of about 350 watts of incandescent lighting, or a 65-watt and 42-watt CFL pair (4200 and 2700 lumens respectively).

A 50 watt incandescent bulb is about 650 lumens.
Power = Voltage x Current, so Current = Power / Voltage. {1 amp = (1 watt)/(1volt)}. At 120 Volts, then Current = (13 watts)/(120 volts) = 0.10833 amps.But at 12 volts, (13 watts)/(12 volts)= 1.0833 amps.
it is hard to describe by words, why not to buy an infinite bright flashlight to compare. I know a flahslight with displaying lumens. It is DDT40 imalent. from 5 lumens to 4000 lumens you could find a way to compare gradually. by the way, one lightening candle is a lumens.
Mitsubishi HC3900 with 3000 ANSI Lumens....best!
